To all rwhom. t m (1,1/ concern.'

.lle it known that lf, TiioMas J. lVImLnN, a citizen ot the UnitedStates o' America, and a resident o't New Brunswick, county oll\'lidd`lesex, and State ot New Jersey, have invented a new and usefulTire-M/akingr M ation.

lifty invention relates `'to machines for makv ing' ijnieinna'tic tires,more, .especially for ma king shoes otl clench'er and (prick-detachabletypes for pneumatic tires, and comprises improved tool-holding means.

The machine. herein illustrated and de stai'bed embodies imprfwements onthe machine for the same purpose illustrated and described in my priorai'iplication, tiled Sept.

i910. nu. 592,186.

The objects of my invention are, to facilitate the operation o't thevarious tools of the machine, to :facilitate the application ot beadstothe partly-formed tire shoe, and in general, to produce a machinewhich is exceedingly easy to operate and which is eapablc ot' rapid andhigh-grade work.

l. `will now )z'oeeod to describe my invendrawings, in `which oneconstruction ot ma` chine embodying my invention is illustrated, andwill then point out the uoi'el 'features in claims.

.ln said drawings: Figure '1 shows a side elevation of my improved tiremakino' Inacliine, Figi. shows a top view thereoi'; Fig. $23 shows atransverse. sier-.tion thereofE through the chuck and core. Fig'. it isa view similar to Fig. Si, except that the chuck is not, shown insection, and except that. the i'ornis tor applying` thebeads are shownin place on the chuck. Fig'. 5 is `a face view ot one of the Fig. (ishows a 'tare View o'f'the saddles` for carryingr the toolalfms, inplace ontheir guide. Fig. 7 shows a cross section of the con'ipletedshoe. Fig. ,8 is a detail View, partly in section, illustrating theswivel-connection of the. tools to the toohearryinfr arms.

In the drawings. l designates the main revoluble shaft ot the machine.,2 a `trame in which said shaft is rcvolubly mounted, 2i a `rear wheel onsaid. shaft, 4 a pinion intermeshing with said gear 3 and mounted on ashat't 5, and t5, 6, belt pulleys, one tight; and ,r c loose, on shaft5, for applying power to drive the same.

7 designates a chuck, on shaft l, designed to receive a core on whichthe tire shoe is formed. 8, 8, de isjignate the jaws or arms of saidchuck. c

9 designates a ringcore, upon which the tire, shoe is to `be formed,mounted on Said chuck. i

l() designates a supply roll from .which a strip of mlbber-saturatedfabric is drawn, duringr the making of the shoe, and l1 designates theslir'tt on which said roll is mounted.

l2 designates the fabric strip.

li designates a wrapper roll, upon which a strip ot' fabric, interwonndwith the layers ot strip 12 on roll 10, is wound up as fabric l2 isdrawn from roll 10.

lt designates a shaft on which wrapper roll 13 is mounted, and l5, l5designate guides i-n which shaft .let may move radially to or :from thesupply roll 10. `lllrapper roll 13 is'driven by frictional contactwitilrthe roll of fabric on roll 10. On shaft 11 of roll 10 a frictionbearing box, 20, which may he set up by means of screws 21, is providedtor regulating thctcnsion under which the fabric is drawn 'from rolli(l.

41 designates a table or support, located substantially in line with thecore E) and supply roll 1t), and |n'ovided with guides tor a carriage3S, which may be moved toward and trom said core f) by means of a screw#l2 and lu1nd-\\'lieel a3. This carriage 3S is provided with a guide 38`for two saddles it?, to which are pivoted tord-carrying' arms Iii, I-land titi. These arms are provided with longitudinally adjustableextensions, il, 3Q and 323, respectively, to which various tools usedvin forming the tin` may be secured. l have indicated a bead-rollingroller 2U on one oi said arms, and a trimminglr knife 2t) on another ofsaid arms. It will be understood that duplicate tools are provided onthe two sides ot the core.. The tools are preferably swivel-` conneetedto their respective arms, as indi-l :ated in Fig. 8, which shows a yoke5t) tor holding' the beadaolling roller 26, swivel-' connected to itscorresponding arm.

lin so tar as yet described the n'iacliine is substantially the same asthe machine illustrated and descrilicd in my said application Si'. No.582,186. I will now proceed to describe the features in which themachine herein described diil'crs t rom that of my said priorapplication.

ln the nuichine herein illustrated and desiiilwil. the tivo saddles,il?, carrying:` the tool--ffi'ryiiig zirins, are provided with sepaHrate feci irs Ill? and hand-wheels l0, for inciting-g ,sul sfuldlestoward und ironi each other, and each tord-carrying arin,l 3l, or

5353, or I-l, has pivoted to it a brace, (55, the 'fi'ceend of vvliu'fhis adapted to engage one ui' :mother of a series of teeth, (3G, formedou the Vhice oi." the corresponding saddle This construction permits thesaddles themselves, sind the feed screws by which they are uioi'eil, tobe used to press the various tools against the work. An arm, 34: or 35or Lili, having been nio'ved to such position thii itstool is inproximity to the work, and the ijcoi'responiliiig brace, 65, having beenengaged with a tooth 6G of the saddle, so as to prevent the arm fromswinging back, the corresiviouding feed screw, 39, is rotated' so toinove the saddle toward the center, thereby vpressing the tool tightlyagonist-r, the work; and by turning such feed sereW he tool mv beadvanced or retracted, fromv iiine to time, may be required. l

The described construction of tool-hold! ing and operating; ineens,constitutes a very siinple but powerful ineans for holding the tools totheir Work. By disengaging the brace of any tool arm from the teeth 66,that tool arin may beswung back out of thway, and another ltool erininay then be swung up close 'tothe Work and its brace engaged with'tooth 6"'. It is therefore'very easy to change from one ltool toanother, and no adjustment of the tools, after they are once setproperly, is required While Working on any one size and style of shoe.The 'tivo saddles 37 being entirely separate and distinct, the Workmenon one side` of the machine advances and retreats his tools entirelyindependent of the actions of the workman von the other side, and canexert such pressure of the tools against the work.

as' conditions may require.

VFor apply/iisg,` beads to the two sides of he shoe, during the i-nakingof the shoe, l. u'efelriibly einploy yzu'niular forms 23, adaptd to litover soine'ineniber of the machine, for example, the chuck 7, wherebythey may iceiitereifiiilh resl'iect to the shoe in procofcoruitruciioii. Before placing these furnis airaiust a. partly formedshoe, a. previously-iornwd bead-ring, 2Q, of suitable material, jsmounted on the periphery of .cru-h 'oriu -Wg and it is then easy totransl'i'i' such lar-ruining to the partly formed tire, by mounting' theforni on the chuck, pressiue il against the'partly-formed shoe, and thenpressing thc bend-ring against the pa:ily-formed shoe, with a suitabletool,

.while ille cure S rotates, so causing the Inruil-rhin to adhere tothe'shoe the forni -y nuiy be removed.

l lerelefore, in machines for forming tireafter w bien recibes shoestheheads have usualiy been applied iroin continuous bead-strips, fed to theshoe by iucaiis of carefully adjusted feeding devices. 'lhe applicationof the beads in this uajv is e somewhat delicate operation. ApplyinpArthe beads in the nienner herein de scribed, by ineens of the forms 23,is .a inuch simpler operation, which may be per foi-ined inuchmore'rapidly, and the beads, when applied., are applied in precisely theproper place, and are truly concentric. t is a very'easy matter to fornithe bead-rings before placingthem on the forms, and such rings inuy bemade by unskilled labern` ln formingtire shoes by ineans of the niachineshown and described herein, the method of opera-tion is as follows: lTheringcoie, 9, is first coated with rubber cement,

`and the end of thefebric-'strip, 12, is drawn from roll 10 and appliedto the ring-core, and the ring-core is lthen set in rotation, so Windingthe fabric-strip upon it; and. as the fabric is so Wound on the core,the workmen, with hand-tools, termed spades, press the fabric in againstthe under side of the ringcore. The tension with which the fabric l2 isdrawn lfrom the roll -10 may be relied upon to insure tight lWinding ofthe fabric on the core, 5or, if necessary, pressure rollers, applied byhand or otherwise, may be used for rolling down the fabric as theWinding proceeds. Ajfter'a suitable number of layers of the fabrics-havebeen Wound upon the core in this nianiier (two layers .are usually .con-

sidered suflioient), the bead-rings Q2 are applied in the mannerpreviously describe and the Winding of the fabric is continued,

,the fabric being now caused-to cover the beads. Groove'd beederfecting,rolls, 26, Carried by4 certain of athe tool arms, are also pressedagainst the beads, by the means hereinbefore described, and by their.pressure perfect the forni of the beads and 'also press the outerlayers of fabric tightly aga-inst t'he beads, so causingthe variouslayers ofabric tondhere iightly. After a suilicient number of theseouter layers of fabric have been applied, the strip of fabric l2 is cut,its end pressed tightly down on the layers of fabric beneath, and one orinorevlayers of guiii are applied to the outer portion of the tire toform what is tei-ined the padding. This padding usually covers theentire outer surface of the carcass as so fair formed, from the bead onone side thereof to the bead on the other side thereof. Such leyer orlayers of gum may be applied by hand, or, and preferably, may be appliedby substituting in the machine, for the f bric sup ply roll l2, anothersupply roll carrying al giuri strip. The gum is wound upon ythe partlyVformed carcass in the came Way as the fabric', 21nd, usually, islpressed 'down tightly as so Wound, by rollers held by hand or otherwiseagainst the carcass.
